Kitchen Fire Suppression Canister Self-Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial kitchen fire suppression systems require external devices and pressure sources to actuate the main control valve of the canister, adding complexity and cost.
Innovation Solution
The system uses internal pressure from the canister containing the fire extinguishing agent and gas expellant to actuate and open the main control valve, eliminating the need for external devices and pressure sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external source or mechanism is employed to actuate the main control valve of the canister, then the canister can be actuated to release the fire extinguishing agent, but additional cost and complexity are added to the system
Solution Approach 1:
The canister system uses its own internal pressure to actuate the main control valve, eliminating the need for external actuation mechanisms. The high-pressure gas compartment naturally pressurizes the low-pressure actuation compartment through the control valve, causing the valve to open automatically when the solenoid valve is energized. This self-service approach reduces system complexity while maintaining reliable actuation.
Solution Approach 2:
The invention merges the propellant function and the actuation function into a single integrated canister system. The same internal pressure that propels the fire extinguishing agent is also used to actuate the control valve. By combining these functions and using the solenoid valve as a simple control element rather than a complex external actuator, the system achieves both reliability and simplicity.
2Reliability
If an external source or mechanism is employed to actuate the main control valve of the canister, then the canister can be actuated to release the fire extinguishing agent, but additional cost is added to the system
Solution Approach 1:
The system uses its own internal resources (high-pressure gas) to perform the actuation function, eliminating the need for separate external actuators, motors, or complex mechanical linkages. This self-service approach significantly reduces manufacturing costs while ensuring reliable actuation through the natural pressure differential.
Solution Approach 2:
The invention extracts the actuation function from the external system and integrates it into the canister's internal pressure system. By taking out the need for external actuators and using only a simple solenoid valve to control the pressure release, the system reduces manufacturing complexity and cost while maintaining reliable operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This simplifies the system, reduces costs, and ensures reliable actuation of the fire extinguishing agent release in response to fires or potential fire conditions within the kitchen.
Implementation Method 1
the internal pressure within the canister containing the fire extinguishing agent and gas expellant is employed to actuate and open the main control valve of the canister
Implementation Method 2
The solenoid valve is energized and its state is changed to where the activation line is open, exposing the main control valve of the canister to the internal pressure of the canister

AI summary
The present invention relates to a fire extinguishing system for a commercial kitchen. The fire extinguishing system comprises a canister containing a fire extinguishing agent and a gas expellant. In the event of a fire or conditions that pose a threat of a fire, the internal pressure in the canister is utilized to actuate a main control valve of the canister which releases the fire extinguishing agent from the canister.
